HU 767 1979.7700: This measure is an average of a power spectrum and an
autocorrelogram measure, listed separately by McAlister & Hendry. McA1982d
1980.7257 This measure was incorrectly attributed to ADS 13944 by
McAlister et al. (1983). McA1983
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 3.96 +/- 0.66, 3.40, and 1.82 Msun, respectively. Mlk2012
